A pressure vessel that has a volume of 10 m³ is used to store high-pressure air. (a) If the air pressure and temperature inside the vessel are 20 atm and 300 K, respectively, what is the mass of air store in the vessel? (b) When the air in the conditions of part (a) is heated to increase the temperature to 600 K, calculate the change in entropy of the air inside the vessel starting from the following two equations separately: S₂ - S₁ = Cpln (7/2) - n (72²) – Rln (¹/²) Compare the results and discuss if those are same or not. (7/2) - Rin (22) S₂-S₁ = C₂ln( The constant pressure heat capacity (Cp) of n mol of an ideal gas is given by (3/2)nRu, where R., is the universal gas constant. The 2 mol of an ideal gas at a constant pressure changes its temperature from 100 K to 300 K. Find the AU, AH, q, and w for this temperature change. The constant volume heat capacity (C.) of n mol of an ideal gas is given by (1.2)nR where R., is the universal gas constant. The molecular weight of this gas is given by 1 g/mol. The 2 mol of an ideal gas at a volume of 21.0 L at 300 K expands adiabatically and reversibly to a volume of 43L. Find the AT, AU, AH, q, and w for this expansion.
